Creusa bore Hypseus, the future king of the Lapiths, and Stilbe to the river god Peneus.[2] Through Hypseus, she was the grandmother of Cyrene, one of the best known lovers of Apollo while her daughter, Stilbe, gave birth to twin sons to the same god. These sons were Lapithes and Centaurus progenitors of the warrior tribe, Lapiths and the wild half-beasts, Centaurs.
In another version of the myth, Creusa was called the daughter of Peneus and Naïs.[3] According to Pherecydes, the latter was also the reputed mother of Hypseus by the same river god.[4] In one account, the mother of the Lapith king was called Philyra.[5]
“He (Peneus) lay with the nymph named Creüsa and begat as children Hypseus and Stilbê, and with the latter Apollo lay and begat Lapithes and Centaurus.”
